-main metabolic transformations;
- hormonal regulation of metabolism in feeding and fasting.

The main competence will be:
- to evaluate the nature and properties of reagents and solutions usually employed in professional practice;
- to understand the general metabolic behavior in physiopathological conditions
Prerequisites
For an effective understanding of the topics of Biochemistry, the basic knowledge at high school level of Chemistry and Biology is required. In particular, general knowledge of cell structure, atomic structure, simple inorganic and organic molecules structure, are mandatory.
Teaching methods
The course is organized in lectures on all the subjects. Students are stimulated to interact with the teacher during the lectures.

Learning verification modality
The exam consists of a written test possibly followed by an oral examination relative to the three modules of the integrated course.

The written test, comprising basic questions covering all the topics, aims to assess the minimum basic preparation to face the oral examination.

The oral exam aims to assess the level of knowledge of the subjects of the integrated course, and the ability to make connections and to integrate knowledge, also in relation to the nursing professional activity. The oral exam will also test the student communication skills.
